Kernel rpms of 2.6.18-194.11.1.0.1.el5 & 2.6.18-194.26.1.0.1.el5 equired

Hi All,
I have an urgent need of following kernel rpm files (not source files) for Oracle Linux Enterprise server machine.
1. kernel-2.6.18-194.11.1.0.1.el5
2. kernel-2.6.18-194.26.1.0.1.el5
My Machine Details, using following commands, are:

Please help me with that.
Thanks in advance!

Downloading a kernel from anywhere else is just a massive security risk. If it's not signed by Oracle Development, there is no way you should trust it, unless you compile it from source yourself.

Cant find kernel-2.6.18-194.0.0.0.3.el5

Hi All,
I am looking for the kernel-2.6.18-194.0.0.0.3.el5. Please point me to the link / location where i can find the kernel rpm - kernel-2.6.18-194.0.0.0.3.el5.

The kernel you are looking for is a kernel patched by Oracle. It is not the standard RHEL 5.5 based distribution kernel.
It is available on the OEL 5.5 installation DVD iso for x86 or x86_64. You can download the iso image from https://edelivery.oracle.com/linux
https://oss.oracle.com/el5/docs/RELEASE-NOTES-U5-en.html
Open the DVD and look inside the Server/oracle_updated directory and you will find:
kernel-2.6.18-194.0.0.0.3.el5.x86_64.rpm among other 0.0.0.3 patches for oracleasm, ocfs2, etc.

Kernel-devel-2.6.18-238.el5.x86_64.rpm dependency for dkms

Hi,
I am trying to install VirtualBox-4.1-4.1.8_75467_rhel5-1.x86_64.rpm on Red Hat Enterprise Linux Server release 5.6.

Any idea?

There is no 'kernel-devel' package on redhat, if you need the kernel source then you need to pull down a srpm.Of course there's a kernel-devel package. I use it all the time.
However, the Red Hat (and associated downstream compilations like CentOS and Oracle Linux) don't use DKMS. What you want is to install kernel-devel so it builds the full kernel modules, not the DKMS module. We provide the kernel-devel package for Oracle Linux on the install media, on ULN and via our public yum repository at http://public-yum.oracle.com

[Mini-HOWTO] RPMs needed to compile a kernel-module on / for VM Server

In reply to the question I've asked a couple of days ago in this forum
Compile module for Oracle VM Server
I tried to do it myself, since no answer was given.
And it turned out to be fairly easy afterward too!
Just install these RPM-packages from an Oracle Enterprise Linux v5 i386 distribution (v5, NOT v5U1!) in this order:
kernel-headers-2.6.18-8.el5.i386.rpm
glibc-headers-2.5-12.i386.rpm
glibc-devel-2.5-12.i386.rpm
libgomp-4.1.1-52.el5.i386.rpm
cpp-4.1.1-52.el5.i386.rpm
gcc-4.1.1-52.el5.i386.rpmThese 6 RPMs and finally the
kernel-ovs-devel-2.6.18-8.1.6.0.18.el5 RPM, to be found on the VM Server-CD you've burned from the downloaded ISO.
Hope this helps!
At least I was able to recompile the qla2xxx-modules from the HP-provided sources.

hbokho

basically it is the same thing as build a normal kernel module i think. some packages need to be installed first for e.g. the kernel source and development packages.
refer to, (just some google results)
http://www.eece.maine.edu/~sheaff/module.html
http://tldp.org/LDP/lkmpg/2.6/html/index.html
The system I installed the OVS on has a network chip
that is not supported by the kernel in OVS 2.1. I
found the source code for the module, but does anyone
have a clue how to set up an environment so I can
compile the module in a way that it'll be accepted on
the OVS server. I downloaded the Source OVS CD, but
I'm not quite sure what to do from there. Anybody has
some hints?

Latest Kernel-uek upgrade

Mostly curiosity on how this kernel replaces the existing kernel by what almost appears
to be an in place upgrade. (2.6.32-100.26.2.el5 to 2.6.32-100.28.9.el5)
After upgrade there are no references in grub for the old kernel and it no longer exists in the rpmdb.
This has happen on both OEL5.6 and OEL6 systems.
It would make the fall back to old kernel process a little more fun.
Anybody have any information on this?

I have not rebooted this box yet so here is the current running kernel.

Kernel/driver downward compatibility

Dear all,
I have an EL5 Update 4 installation. My WLAN card has a BCM4318 chip from Broadcom. As stated on Broadcom's home page, I normally needed a b43 driver--however, this requires kernel 2.6.25 or higher. My kernel is 2.6.18, as originally downloaded from Oracle's web site. It as a deprecated driver bcm43xx installed, modprobe shows it up. However, this driver can not control the above card. LAN is working OK.
My questieon is: Can I get and install a much newer b43 driver to cooperate with my older kernel or is downward compatibility excluded?
Lately I used an up2date for my ULN, no change in kernel.
Then I looked round for latest versions, and downloaded some kernel-2.6.18-164.11.1.0.1.el5.i686.rpm package, When trying to install it I get
Can't install a different arch of /root/Desktop/kernel-2.6.18-164.11.1.0.1.el5.i686.rpm than already installed.
Can anyone help me what to do for me not to damage anything that is already working properly?
Thanks, kind regards,
Miklos HERBOLY

This questions comes up a lot recently.
OEL is a server distribution and is not likely to keep abreast of the latest
wireless technology. So if your wireless card isn't properly detected out of
the box, you are pretty much own your own.
That being said, if you do this:
# /bin/rpm -qa --qf="%{NAME}-%{VERSION}-%{REVISION}.%{ARCH}.rpm\n" kernel\*You will get the exact name of the kernel RPM for your current install. If
you get a newer kernel from somewhere, the VERSION and REVISION portions may
differ, but the rest should be the same as you currently have.

How do you recompile the kernel for oracle linux 6.3

Hello,
I have installed Oracle linux 6.3 default settings on x86_64 bit pc
I have some questions:
1. What public yum repositories contain the oracle linux 6.3 kernel source code ?
2. Is the oracle linux 6.3 kernel source code on OracleLinux-R6-U3-src-dvd1.iso or OracleLinux-R6-U3-src-dvd2.iso , can I use this to recompile a new kernel ?
3. Do you have the steps/commands needed to set options and compile a installable kernel[rpm] on oracle linux 6.3 x86_64.
4. What gui tools are available in the desktop to manage settings e.g sound/volume or to install additional gui utilities.
5. Is there some documentation help on using the oracle linux desktop ?. If so where is it located .
Thankyou
Glenn

3. Do you have the steps/commands needed to set options and compile a installable kernel[rpm] on oracle linux 6.3 x86_64.No, you'd need to decide that for yourself. The kernel source is complex and can be very tricky to recompile.
4. What gui tools are available in the desktop to manage settings e.g sound/volume or to install additional gui utilities.Wow, topic shift. GNOME Control Center manages settings and installing new utilities is done by Pirut.
5. Is there some documentation help on using the oracle linux desktop ?. If so where is it located .Oracle Linux isn't intended to be used as a desktop. All the documentation is here:

I welcome any test I can perform to prove empirically whether it is the uek kernel or not.It's definitely the UEK, for the reasons stated above. Oracle Linux 5 Update 6 was the first version of Oracle Linux to ship with the UEK as the default kernel, and we hadn't quite gotten all the naming aspects 100% correct yet. So, the 2.6.32-100 kernel is absolutely a UEK.
So, on a freshly installed Oracle Linux 5 Update 6 box:
# uname -a
Linux localhost.localdomain 2.6.32-100.26.2.el5 #1 SMP Tue Jan 18 20:11:49 EST 2011 x86_64 x86_64 x86_64 GNU/LinuxIf I then upgrade yum (required to get the yum changes to support kernel-uek installs) and then upgrade the box to the latest and reboot:
# yum update yum
# yum update
# rebootWe're now running the latest UEK Release 1 kernel (2.6.32-400.26.2.el5uek) and it identifies itself as such:
# uname -a
Linux localhost.localdomain 2.6.32-400.26.2.el5uek #1 SMP Tue Apr 23 19:04:54 PDT 2013 x86_64 x86_64 x86_64 GNU/LinuxNotice that it now says el5uek in the uname string.
We changed the RPM and kernel identifiers from kernel-uek-2.6.32-100.35.1.el5uek. So, it wasn't in the release of Oracle Linux 5 Update 6, but happened in that update errata cycle. All subsequence releases of the UEK Release 1 (2.6.32) and UEK Release 2 (2.6.39) identify themselves with an el5uek or el6uek marker.
BTW, is there any particular reason you're using a template that has a particularly old version of Oracle Linux 5 instead of using the latest Update 9? You can find Oracle Linux 5 Update 9 templates under the heading "Oracle VM 3 Templates (OVF) for Oracle Linux 5 Media Pack for x86_64 (64 bit)" on the Oracle Software Delivery Cloud.

Oracle Linux 5.6 - Do I need to keep the xen kernel ?

I am using the Oracle Linux 5.6 kernel 2.6.32-100.26.2.el5 also know as the UEK Release 1 in an OVM x86_64 environment.
Question: Since the Guests are paravirtualized and require Xen specifc I/O drives ( network, disk, etc. ) does that mean I need to keep the Xen kernel rpms, i.e.,
kernel-xen-2.6.18-238.0.0.0.1.el5
kernel-xen-devel-2.6.18-238.0.0.0.1.el5
and this entry in /boot/grub/grub.conf
          title Oracle Linux Server (2.6.18-238.0.0.0.1.el5xen)
          root (hd0,0)

         initrd /initrd-2.6.18-238.0.0.0.1.el5xen.img
The main driver for this question is I am trying to determine if these rpms are accessed in any way when the UEK Release 1 is in use. If so, then I will need
to heed to the Security Scan results against the xen kernel version otherwise I will ignore them and move forward.

https://oss.oracle.com/el5/docs/RELEASE-NOTES-U6-en.html
Hardware virtualized guest with kernel-uek-2.6.32-100.35.1.el5uek and higher
Unbreakable Enterprise Kernel version kernel-uek-2.6.32-100.35.1 adds support for paravirtualized drivers in a harware virtualized guest on Oracle VM. Starting this kernel version hardware virtualized guests which are not configured to use paravirtualized drivers will need an additional kernel boot parameter "xen_emul_unplug=never" in /etc/grub.conf:
kernel /vmlinuz-2.6.32-100.35.1.el5uek ro root=/dev/VolGroup00/LogVol00 xen_emul_unplug=never
With kernel-uek-2.6.32-100.35.1 and higher, the default is to present only paravirtualized drivers when running in a hardware virtualized guest on Oracle VM. Adding this kernel boot parameter makes the kernel also present the emulated drivers as it did before (e.g. the 8139cp network driver may no longer load if this parameter is not set).
Older version of Unbreakable Enterprise Kernel do not have support for hardware virtualized guest that uses paravirtualized drivers (PVHVM).

If you are running OEL-4 (2.6.9 kernel) and you have an ULN account, you can download kernel-sourcecode rpm from ULN. There is no kernel-sourcecode for OEL-5 available on ULN site.

Why is kernel-2.6.9 (OEL-4) faster than kernel-2.6.18 (OEL-5) ?

Hi,
as long as RHEL-5 and then OEL-5 have been released, I have been wondering why my own programs, compiled and run on RHEL-5/OEL-5, are slower than the same programs compiled and run on RHEL-4/OEL-4 on the same machine. This is really barmy since gcc-4.1, shipped with RHEL-5/OEL-5, is very aggressive compiler and produces faster binary code than gcc-3.4.6, shipped with RHEL-4/OEL-4. I verified this hundred times testing both compilers on RHEL-4/OEL-4 and RHEL-5/OEL-5. The 4.1 compiler always produces faster executable on the same OS.
The problem is obviously in kernel-2.6.18. There is something in the kernel (maybe scheduler?) that slows down the execution of programs. But what? I experimented with changing various kernel boot parameters (eg "acpi=off" etc), even tried to recompile the kernel many times with various combinations of config parameters, and nothing helps. Thus, I'm still wondering whether the problem is solvable by disabling one or more config parameters and recompiling the kernel, or is deeply embedded in the main kernel code.
Is there anybody in this forum who experienced the same, say running OEL-4 before migrating to OEL-5?
Here are two examples showing different execution times on OEL-4.5 (kernel-2.6.9-55.0.5.0.1.EL.i686, gcc-3.4.6-8.0.1) and OEL-5 (kernel-2.6.18-8.1.10.0.1.el5, gcc-4.1.1-52.el5.2). The first example is trivial but very sensitive to overal system load and kernel version. The second example is "Sieve of Eratosthenes" - the program for finding prime numbers (CPU bound).
EXAMPLE 1.
/* Simle program for text screen console */
/* very sensitive to overall system load */
/* and kernel version                     */
#include <stdio.h>
int main(void)
    register int i;
    for(i = 0; i < 1000000; i++)
     printf(" %d ", i);
    return 0;
/* end of program */
$ gcc -O2 -o example1 -s example1.c
$ time ./example1The average execution times on OEL-4.5 and OEL-5 are as follow:
Mode      OEL-4.5         OEL-5
real      0m3.141s        0m4.931s
user      0m0.394s        0m0.366s
sys       0m2.747s        0m4.563s
----------------------------------As we can see, the program on the same machine, compiled and run on OEL-4.5 (gcc-3.4.6 and kernel-2.6.9) is 57% faster than the same program compiled and run on OEL-5 (gcc-4.1.1 and kernel-2.6.18), although gcc-4.1.1 produces much faster binary code. Since the times the process spent in user mode are almost equal on both OS, the whole difference is due to the time the process spent in kernel mode. Note that kernel mode (sys) is taking 66% more time on OEL-5. It tells me that "something" in the kernel-2.6.18 slows down the execution of the program.
In the second example OEL-4.5 is also faster than OEL-5, but the differences in execution times are not so drastic as in the first example.
EXAMPLE 2.

    if ((sieve_array = (char *) malloc( (size_t) (MAX_PRIME_AREA + 1))) == NULL)
     fprintf(stderr,"Memory block too big!\nMemory allocation failed!\a\n");
     exit(EXIT_FAILURE);
    for(count = 0; count < REPEAT_LOOP; count++)
     for(prime = 0; prime < (MAX_PRIME_AREA + 1); prime++)
             *(sieve_array + prime) = (char) '\0';
     for(prime = 3; prime < (MAX_PRIME_AREA + 1); prime += 2)
         if (! *(sieve_array + prime) )
          *(sieve_array + prime) = (char) 'P'; /* offset prime is a prime */
             for(composite = (2 * prime); composite < (MAX_PRIME_AREA + 1); composite += prime)
              *(sieve_array + composite) = (char) 'X'; /* offset composite is a composite */
        /* DO NOT COMPILE FOR TEST !!!
        fprintf(stdout, "\n%d\n", 2);
        for(prime = 3; prime < (MAX_PRIME_AREA + 1); prime += 2)
            if ( *(sieve_array + prime) == 'P' )
                fprintf(stdout, "%d\n", prime);
    free(sieve_array);
    return 0;
/* End of Sieve of Eratosthenes */The average execution times on the same machine on OEL-4.5 and OEL-5 are:

An hour? Hard to believe or is your hardware that
old?An hour? That's a super good time for 3 kernel
packages (i686, xen and PAE) with all modules, plus 3
kernel-devel packages, plus debuginfo package of
150-580 MB where smart people at Red Hat decided to
put uncompressed vmlinux image which is necessary for
kernel profiling and debugging. Ah, I had a different kernel make process in mind.
Oracle doesn't ship
debuginfo package. Of course, this is when I build a
"complete suite" of kernel rpm packages using
unmodified spec file. And, to be honest, it takes
much more than an hour, maybe even two hours. Another
thing is compiling single i686 kernel without
building a package. But it also takes at least half
an hour. Anyway the time significantly depends on how
many modules are selected to be built in.That what I was looking for.
What's your time to build a single kernel (which
version?) with default set of modules ? On which
hardware ? I've only access to a root server right now, which is

Kernel-firmware package

I compiled the whole kernel package for OEL5.7.
But on installing the RPM, I get this error:
rpm -vih /usr/src/redhat/RPMS/x86_64/kernel-uek-2.6.32-200.20.1uek.x86_64.rpm
error: Failed dependencies:
kernel-firmware >= 2.6.32-200.20.1uek is needed by
kernel-uek-2.6.32-200.20.1uek.x86_64
Yet I see no kernel-firmware package that was compiled into an RPM
as part of this. I compiled using:
rpmbuild -ba --target x86_64 kernel-uek.rpm
Any ideas? How do I get and compile the kernel-firmware package?
Thanks in advance.

I know very well how to compile it, so does anyone know where I can
obtain the source for the kernel-uek-firmware for kernel-uek-2.6.32-200.20.1 ?The source for the firmware is contained with the same kernel src you've already downloaded, however it's compiled separately. You need to enable it in the .spec file for the UEK build:
# kernel-firmware
%define with_firmware 0Switch that to 1 and rebuild the kernel RPM from the .spec file.

The beginning of RPM-hell on VM Server [SOLVED]

Check this README regarding the Hypervisor patch:
http://download.oracle.com/otn_software/virtualization/Hypervisor_README
Right. Downloaded the two mentioned files plus an extra "xen-tools" , tried to install as stated in the above readme and this shows up:

Please Oracle, be a little more straight in providing the right RPM's (unless I'm overlooking something completely). This update is useless so far...
Am I the first to bump into this issue?

Missing RPM xen-devel was added to Oracle downloads.

The current version is very buggy. Hopefully Oracle will release new version or patches.
My notes:
1) VM has gone craizy and shows initializing..., for 4 days already, cannot delete it, cannot delete server nor cannot delete server pool :)
2) Use case: Power on to VM, initializing..., restarted VM server and now it's not possible to stop server pool, delete server pool and also not possible to delete or shut down virutal machine that is still initializing. So only solution I found is to reinstall server.
3) Power on VM and VM got the status Running, Power OFF vm, Power ON and no more able to power up. Shows only initializing
